Abstract: 749,020. Photographic developing apparatus. OZALID CO., Ltd. Dec. 9, 1954 [Dec. 11, 1953], No. 25192/63. Class 98 (2). Apparatus in which prints are developed by ammonia vapour while being passed over the perforated surface of an evaporating tank by an endless impervious conveyer belt, and which is provided with a further endless belt or belts meeting the conveyer belt so that the prints after developement may be carried upwards between the two belts for delivery to a tray positioned above the conveyer belt, is provided also with guiding means across the gap between the side of the tank and the forwarding run of the delivery belt, these means being designed to avoid risk of a print, which has become curled during development, failing to make contact with the delivery belt, and being such as to provide line contacts with the under surface of the developed prints. As shown, the impervious conveyer belt 13 running around rollers 14, 15, 16 over the perforated surface 12 meets the delivery belt 18 (which may comprise a plurality of thin side-by-side belts) running around rollers 19, 20, 21, 22 at the left of the tank, and guiding means constituting a series of thin plates 25 supported on a rod 26 occupy the gap between the tank and the delivery belt, the plates 25 being parallel to the run of the belts. Parallel wires or longitudinal projections of a metal plate may replace the plates 25. These several means have a minimum tendency to condense water vapour from the tank and so stain the prints. Specification 645,895 is referred to.

Title: Improvements in valved coupling for fluid conducting lines
IPC: F16L37/12
Filed: 1948-10-01
Abstract: 649,493. Pipe couplings. KRONE, H. C., and MEYER, W. Oct. 1, 1948, No. 25656. [Class 99(i)] [Also in Group XXIX] In a pipe coup ling comprising members 10, 11 adapted to be locked together ir axial alignment and normally closed by valves 31, 50 respectively the valves are actuated by ar axially disposec stem 39 which moves the valves in opposite directions, the locking means and the stem being so related that the valves cannot be opened until locking is effected and the locking means cannot be released until the valves are closed. The stem 39 passes through a locking stem 24 which is secured to the member 10 and has an axially slidable locking collar 56 rotatably mounted on it. The part 10 has a bevelled sleeve 14 which is passed through a lateral opening in the part 11 and engages the flanged wall of a semicylindrical section 17 on the latter. The locking stem 24 is held by left hand threads in a boss 22 on the member 10 and has a grooved extension 28. The actuating stem 39 is threaded into the valve 31 which has a shank 33 slidably guided in the member 10 whilst the valve 50 is guided in the member 11. The collar 56 provides a seating for a coupling yoke 61 which is connected to the sleeve 14. Mounted on the collar 56 is a wheel 65 which has a housing 67 for a slidable spring-loaded latch bolt 68 which normally locks the wheel to the collar. Slidably but non-rotatably mounted on the stem 39, is a spring-loaded key 75 which normally interlocks with the extension 28. When the parts are uncoupled the wheel 65 is locked to the collar 56 by the bolt 68 and the key 75 interlocks with the stem 24 preventing the stem 39 from turning. Locking is effected by turning the handle 65 whereupon the collar 56 moves up the stem 24 until the valves abut, the key 75 slides up the stem 39 to disengage from the extension 28 and the latch bolt 68 bears against a handle 74 for the stem 39. The handle 74 is now turned and the valve 31 travels up the stem 39 until stopped by a shoulder 36 whereupon the valve 50 is opened. The wheel 74 also forces down the bolt thereby unlocking the wheel 65 and the collar 56 so that the parts 10, 11 cannot be uncoupled until the valves are closed. Seals are retained in the valve seats by an overhanging lip 82.

Title: A die set construction
IPC: B21D37/10
Filed: 1958-08-11
Abstract: 841,810. Punching; stamping; sub-press mechanisms. CONNER, G. O. Aug. 11, 1958, No. 25719/58. Class 83 (4). [Also in Group XXXIV] In a die set comprising spaced-apart plates with a polygonal pin carried by one plate and a pin guide housing carried by the other plate, pin guide segments disposed in the pin guide housing are movable about the axis of the pin for self-alignment with the sides of the pin when the pin is inserted into said housing. A square leader pin 11 on an upper die set plate, Fig. 1, carries a bearing assembly comprising four retaining-plates 40 with bearing rollers 41 secured in apertures 42 by upsets 43, Fig. 2. The bearing retainers 40 are pivotally secured together by pins 49 passing through projections 44, 46 or, alternatively, links of resilient wire may be used, the complete bearing assembly surrounding the leader pin 11 and being secured to it by the engagement of a boss 52, Fig. 5 (not shown), against a shoulder 56 on the pin. The leader pin 11 and the attached bearing assembly are received between four segmental guides 25 mounted inside a guide housing 17 attached to the lower die set plate 15, Fig. 3. The segments 25 are circumferentially biased apart by springs 30 or alternatively by rubber strips received in grooves in the segments, so that on entry of the bearing assembly, the segments may move circumferentially until the bearing faces 26, Fig. 4, are aligned with the faces of the leader pin, thus taking up slight inaccuracies in the latter. After alignment, screws 35 which fit for slight lateral adjustment in apertures 33 in the housing are tightened to draw the segments against the inner walls of the guide housing 17. The segments 25 are axially retained in the housing 17 by clips 21 or by a boss 32. Leader pins and guides of the type described may be incorporated in apparatus having relatively moving members carrying forming dies such as presses and sub-press mechanism, as disclosed in Specification 669,465.

[Class 18] A collapsable box for fruit &c. having folding down sides and ends, has a pliable handle 3 secured to one side 1 with the free end 5 of the handle passing through a slot 6 in the bottom of the other side. The slot 6 may be placed out of centre with respect to the handle, so that the handle springs to a central position when the free end is pulled through the slot. The handle is thus prevented from pushing back through the slot. An additional strip 7 is secured to the side containing the slot to form a pocket for the free end of the handle. The ends 2 may fold inwardly when collapsed, or, as shown, may fold outwardly. Reinforcing pieces 9 may be provided on the ends 2 and are folded over the ends to make them rigid when erect.

Title: Improvements in and relating to pulse-generators
Inventor: CORBETT JAMES PATRICK
IPC: H02K39/00
Filed: 1956-08-24
Abstract: 866,105. Circuits employing bi-stable magnetic elements. ENGLISH ELECTRIC CO. Ltd. Aug. 26, 1957 [Aug. 24, 1956], No. 25942/56. Class 40 (9). [Also in Group XXXV] A pulse sequence detector employing bistable cores 38, 39, 40 produces single impulses at L or R from trains of three sequential impulses from a three-phase inductor alternator 25, 26, 27 (see Group XXXV) for indicating the direction and speed of movement of a work-table (see Specification 866,114, Group XXXVIII). The letter, A or B, beside an input winding on one of the cores signifies the polarity to which that winding tends to turn the core, each winding being connected in series with a rectifier so that it can only receive impulses in one direction. Similarly, the letter beside an output winding, each of which is also connected in series with a rectifier, signifies that they produce an impulse on change to that polarity. Input coils 41 on cores 38, 40 have more turns than coils 42 so that the impulses direct from phases 25 and 27 can override those derived from core 39 when these are coincident. At the beginning of a sequence, say in the order 27, 25, 26, the cores are all in the A condition. The impulse from 27 changes core 39 to the B state so that coil 47 delivers an impulse to coils 42. This changes core 38 to the B state, which has no effect on its output coil because of the rectifier in the output circuit L, but it has no effect on core 40 which stays in the A state because of the overriding effect of coil 41. Thus the impulse from phase 27 produces no output. The next impulse from phase 25 produces no effect in core 39 by coil 45 since this is in the B state already, but it converts core 38 to the A state by means of coil 41 and so generates an output impulse at line L. The next impulse from phase 26 serves to convert the core 39 to its A state in readiness for the next sequence. Similarly, impulses in the reverse sequence 27, 26, 25 produce impulses from phase 27 through core 40 at line R.
